<p>The reservations of occupations of the horizontal (Hi) and vertical (Vj) links of the connection matrix (S/T) having to be selected in order to permit the transfer of incoming cells, each one to at least one outgoing artery (Sj), are recorded in an occupation table (TAB-OCC ET PRIO), for each one of a given number of transfer periods. For each new incoming cell, a transfer period is selected during which the horizontal link and the or each vertical link, selection of which is required to ensure the transfer of this new incoming cell, are free in the occupation table, the occupation of these links is marked in the occupation table for the selected transfer period, and the time shift with which it will be possible to effect the transfer of the new incoming cell is determined. With each new transfer period, the occupation table is shifted, the horizontal and vertical links for which occupation was recorded in respect of this new period are selected, and the cells whose transfer is to be carried out during this period are read from the memories of the input circuits, the reading of a cell being delayed, relative to its recording, by a quantity corresponding to the time shift determined in respect of this cell. <IMAGE></p> |
